Synoptic interface
Synoptic interfaces are controlled by an I/O or input + 8OC module, using three OC outputs. There are three
different versions available, which can be used to show the status for each zone (open, closed or alarm –
memory), using LED’s.
Product number Description:
004440
Synoptic tablet circuit board supplied with 48 LED’s
004442
Synoptic tablet circuit board (in casing) supplied with 8 LED’s
004444
Synoptic interface circuit board with 48 OC outputs
Product 004440 is a large circuit board (175 x 210 mm) with 48 LED’s placed on it. You can connect up to
two of these circuit boards in series to show the status off all 96 zones.
Product 0004442 is small circuit board (67 x 92 mm) in a small plastic casing with 8 LED’s placed on it.
The LED’s on this circuit board can also be controlled directly from an OC output, for instance for section
indication. The circuit board is supplied with clamps for connecting up the OC outputs. When this is done,
some print lines will have to be cut through as well. (See wiring diagram) When these print lines have been
cut, this circuit board can no longer be used for synoptic indication. When the circuit board is used as a
synoptic tablet, up to 12 of these circuit boards can be connected to each other, showing the status of the 96
zones.
Product 004444 is a circuit board (160 x 99 mm) with 48 OC outputs. These outputs can be used to control
LED’s or relays. When LED’s are connected, these have to be connected in series with a resistor of e.g. 1K
ohm. The outputs can supply no more than 100mA each. Keep in mind that an I/O module can only supply
up to 3,0 Ah! The circuit board can be connected to an I/O module and an input + 8 OC module. When 48
LED’s with a 1K-ohm resistor are used, the total power drain will be about 490mA (48 x 10mA + 10mA).
Wiring a synoptic tablet interface
Attention: The maximal cable length between the interface and an I/O or input + 8OC module is 10 meters
.
All synoptic interfaces are connected similarly. The interface is connected to open collector outputs AL6,
AL7 and AL8 of an I/O or input + 8OC module. These outputs are connected as follows:
AL6
to CLK (clock)
AL7
to
DATA
AL8
to STB (strobe)
Also the 0V and +12V must be connected to the I/O or input + 8OC module. Keep in mind that when all
LED’s are burning, 96 in total when 2 interfaces are used, the power drain will be about 1,0 A.
An I/O or input + 8OC module connected to a synoptic interface MUST be supplied with a special EPROM.
This EPROM ensures that all regular functions work properly, and reserves outputs 6, 7 and 8 for connection
to a synoptic interface. There are several EPROM’s available.
